Critical Temperature (Tc) The maximum temperature at which a gas can be converted into a liquid by an increase inpressure. Critical Pressure (Pc) The minimum pressure would suffice to liquefy a substance at its critical temperature. Above the critical pressure, increasing the temperature will not cause fluid to vaporize to give a two-phase system. Critical […]
